3 Claims.

for the supporting of the bases of the inclined frame angles of the hopper upon the tank top and the angle connection between same for obtaining a rigid corner construction to withstand the abuse of the clamshell bucket in the loading and unloading of the ship.

Another object of the invention is to provide said construction in order to make it possible to eliminate the need, as heretofor, for using brackets'for supporting the bases of the frame angles and thereby also the welding of such brackets to the bilge floor plates, and thus reduce the weight of materials used and the cost of the labor.

With the above and other objects in view, the invention will be hereinafter fully described with reference to the accompanying drawings, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a diagrammatic transverse section of one side of the hull of a ship with my invention applied thereto,

Fig. 2 is an elevation of a segment of Fig. 1,

Fig. 3 illustrates in cross section, on an enlarged scale, the angle construction shown in Fig. 1,

Fig. 4 is a similar view to Fig. 3 looking towards the inner side of the hopper, and

Fig. 5 is a similar view to Fig. 3 of the connection of the frame angles to the deck.

Referring to the drawings, I represents the hull of a ship and 2 a side thereof. The hull having the usual keelsons indicated by 3 and 4, and the floor plates 5. The top of the tank is constructed of inverted channels 5, which are arranged transversely flange to flange and welded 2 of the channels 6 over and beyond the side keelsons 4, when said frame angles are placed in the desired inclined positions. The upper endsof the frame angles I2 are. cut off on a horizontal line parallel to their bases It as at I! for con.- nection to the deck I8 of the ship by a suitable angle bar I9 preferably by welding. .A strut 20 extends from the side of the ship to each of the inclined frame angles I2 for supporting same. For the purpose of connecting the bases I6 of the frame angles I2 to the ledge II of the end extensions 8 of the channels 6 when said bases are infull and complete contact with said ledge, the webs I4 of said frame angles are notched at 22 a sumcient depth to receive the upper porthe sides of the hopper I3 are supported by the frame angles I2 and extend from the lower angle bar 24 to the upper angle bar l9, and all parts are connected together by suitable welding and the necessary joints made water tight.

From the drawings and description, it is seen that by extending the ends of the inverted transverse channels forming the tank top beyond the supporting side keelsons provides longitudinally extending ledges for supporting the bases of the inclined frame angles of the hopper and thereby eliminates the need for brackets as heretofore used, and by notching said frame angles for receiving the upper portions of the connecting angle bars and overlapping same with the side plate of the hopper, said corner construcinverted channels 6 forming the top of the tank extend as at 8 beyond the side keelsons 4. The side keelsons 4 are notched as at 9 to receive the adjacent flanges I0 of the channels 5. The end extensions 8 of the inverted channels 6 provide a horizontal ledge I I extending longitudinally of the ship for supporting the bases of the frame angles I2 of the-hopper I3.

The frame angles I2 of the hopper I3 consists of a Web I4 and a flange I5 and are cut off at their bases IS on an angle so as to rest upon and contact the ledge I I of the end extensions 8 tions are strong and afford little exposed or upstanding construction to be damaged by the clamshell.

Having fully described my invention, what I claim is:

1. In a tank top construction for ships and the support and connection therewith of the sides of the hopper, the combination of a tank top, the tank top being supported by a central keelson and side keelsons, the tank top having longitudinally extending side ledges beyond the side keelsons, frame angles consisting of a web and a flange, the webs and the flanges of the frame angles extending inwardly relative to the center keelson and resting endwise upon said side ledges of the tank top, the webs of the frame angles adjacent to the tank top ledges being notched, an angle bar having one of its flanges in the notches of the frame angles and its other flange consisting of a web and a flange, the webs of the frame angles extending inwardly towards the center keelson and being cut off on an angle and engaging said ledges and inclining outwardly therefrom, the webs of the frame angles adjacent to the ledges being notched, an angle bar having one of its flanges in the notches of the frame angles engaging each of said ledges and its other flange extending inwardly towards the center keelson and resting upon its ledge, said frame angles and said angle bars being welded to said ledges, plates welded to the webs of the frame angles, and said plates overlapping the flange in the notches of said angle bars and being welded thereto.

3. In a tank top construction for ships and the support thereby of the frame angles for supporting the sides of the hopper, the combination of a center keelson and side keelsons, a tank top consisting of inverted channels extending transversely of said keelsons and supported thereby,

the channels having their ends extending bei yond and overhanging said side keelsons and forming longitudinally extending horizontal ledges, frame angles consisting of a web and a flange, the webs of the frame angles extending towards the longitudinal center of the ship, the frame angles having their bases cut off on an angle and resting upon said ledges and their upper ends inclining away from the longitudinal of the ship, the webs of the frame angles being notched upwardly from their bases, an angle bar having one flange in the notches of the frame angles and its other flange resting upon said tank top and extending towards the longitudinal center of the ship, said frame angles being welded to said ledges and said angle bars being welded to said tank top, plates forming the sides of the hopper welded to the webs of said frame angles, and said plates overlapping the flanges of said angle bars in said notches of said frame angles and being welded thereto.
